Here's a pic with a set of LT275 65R20 Cooper AT3's on 20x8.5 KMC Skitch wheels with 5.34" backspacing, they have about an inch from the tire sidewall to the knuckle and the tires spec out at 34.2" tall. My wheel opening measurements are now 41.5" rear 42.125" front so I gained 1/2" in ride height. I picked up the 3" coils and I'll get them on someday soon and report back.
